It’s an intriguing visual puzzle: hard to get your head round where the photographer was standing. The shadow looks to be taking the photograph, in which case the photograph is not right. I get the sense that the original photographer was flying: coming into land or taking off.

No drones involved here, it's a plain selfie. I think the weirdness is caused by the angle of the sun and it being a higher than usual footbridge, I was standing directly above the central dashed line. I hadn't noticed until I read the comment, but can see where you're coming from.

Here's a ground level view.

Again also here, ingenious! =)

The angle of the light gives it a very high up feeling, cool!

:)))... sieht aus, als wärst Du Teil einer Straßensperre...so mag ich Selfies...klasse gemacht!

This is a very clever interpretation
